This study was carried out to investigate the effect of depth of sawdust bedding and ground material in dairy cattle barn. Treatment included the concrete floor with a 10cm or 30cm sawdust and the earth floor with a 30cm sawdust. Eighteen cows were assigned to 3 pens with 16.5㎥/head bedding area. The results obtained were as follows : 1. The temperature of sawdust bed was highest in the earth floor with 30cm sawdust, and the moisture content of sawdust bed was highest in the concrete floor with 10cm sawdust bed. 2. Cows defecate feces 9.2, 8.7 and 9.3 times a day in 10cm sawdust on concrete floor(10S+C), 30cm sawdust on concrete floor(30S+C) and 30cm sawdust on non concrete floor(30S+ NC) respectively. In average, they excreta 9.1 times/day(85.8%) in the sawdust beds and 1.5 times/day(14.2%) in the feeding alley. 3. The ratio of daily water amount deposited vapor to total water amount deposited in sawdust beds was 74.0%, 61.5% and 47.1% in 10S+C, 30S+C and 30S+NC respectively. 4. N.P.K contents in the sawdust beds were higher for 10S+C compared with other treatments. 5. When 30cm of sawdust was applied on the earth ground NO$_3$-N contents in the sawdust bed was 37.7, 14.1 and 15.0ppm in depth of 30, 60 and 90cm under the ground, respectively, indicating some possibility of water pollution.

The chest X-ray showed solitary pulmonary nodule on right upper lobe and computed tomography of chest demonstrated mass on posterior segmental bronchus of right upper lobe. Bronchoscopic examination revealed that this segmental bronchus was completely obstructed by a yellow and brownish mud like mass, which was identified as an aspergilloma by pathologic examination. Patient had undergone bilobectomy because of persistent hemoptysis. Tracheobronchial apergillosis in an immunocompetent person is very rare disease. then, we report this case with review of the Korean literature.

Synchronous primary lung cancers in the same lobe are rare. Cavitating adenocarcinoma as single lung lesion is unusual. We experienced cavitating adenocarcinoma and squamous cell carcinoma in the same lobe of the lung. The patient was a 74-year-old male with chief complaints of hemoptysis. CT scan showd a central mass in right upper lobar bronchus, obstructive pneumonia, and lung abscess in the right upper lobe. Pathologically, the central mass was a 2.3$\times$1$\times$1 cm sized squamous cell carcinoma, and lung abscess was revealed as a 37272 cm sized adenocarcinoma. The patient was discharged without any specific problem after right peumonectomy.

This paper focuses on the Bijombon Haerampeon written by Lee Eonjin The analysis of the paper is associated with the following: i) the career of Lee Eonjin ; ii) the manuscripts and collected works of Lee Eonjin ; iii) Haerampeon ; iv) Lee Yeonghyu and Nam Ok ; v) and the comparison of the Bijombon Haerampeon and Haerampeon carried in Songmokkwanjip and Songmokkwansinyeogo. Lee Eonjin(1740-1766) was a great poet and better known as one of the four great interpreters in Chosun dynasty. Woosangingbok was the only manuscripts handed down up to now among the works of Lee Eonjin. Woosangingbok ran the Bijombon Haerampeon, 6 pieces of itinery, 3 pieces of poem, 5 pieces of letter. Lee Eonjin visited Japan from the 6th of October, 1763 to the 20th of June in 1764 as a member of Tongsinsa in attendance upon Cho Om. He wrote Haerampeon vividly with five characters what he observed during his stay in Japan. It was composed on board of Ilkido from the 28th of May to the 8th of June in 1746. After Lee Yeonghyu and Nam Ok reviewed Haerampeon, Lee Yeonghyu placed a blue point and circle and Nam Ok placed a red point and circle. Ultimately the result raised the value of Haerampeon. Haerampeon is to be divide into four parts. Four parts are described below: the first part, the geographic features and products of Japan; the second part, the grow of Osaka city and the cityward tendency of world products; the third part, the racial prejudice, religion, and life; and the fourth part, the good neighborly relations with Japan. Finally, as compared with the proofing and difference of three kinds of text, namely, the Bijombon Haerampeon and Haerampeon carried in Songmokkwanjip and Songmokkwansinyeogo, it is approved that the Bijombon Haerampeon is the most correct text and has the value of cultural properties as a national treasure.

Taurodontism is an anomaly characterized by a long and broad pulpal cavity and consumed apical location of the furcation area. This study aimed to determine the prevalence of taurodontism in deciduous molars based on digital panoramic radiographs of children. The study was performed on a sample of panoramic radiographs taken from 2,473 Korean children who visited the department of pediatric dentistry, Yonsei University Dental Hospital between Nov. 2005 and Mar. 2018. Taurodontism was mainly categorized by Daito's method. Using panoramic radiographs, taurodontism was also categorized into mesotaurodontism, hypotaurodontism, and hypertaurodontism. Mesotaurodontism was the most prevalent type. A total of 2,473 panoramic radiographs were evaluated. The prevalence of taurodontism was 5.7% in general, 51.5% in the left quadrant, 48.5% in the right quadrant, 6.3% in the maxilla, and 93.7% in the mandible. The distribution of taurodontism stratified by gender showed a higher prevalence in males. This is a comprehensive study on the prevalence of taurodontism in children using the largest sample size to date.
